Review rev_229efa93f8a54b0aaf04d3e2fbb2424b

{
  "summary": "Reviewed `src/math/libm_math/coshf.rs`, which implements `coshf` for `f32` using range checks, `expm1f`/`expf`, and a fallback `k_expo2f` for large inputs. I found no concrete supply-chain indicators such as install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `src/math/libm_math/asinhf.rs`, a straightforward `f32` inverse-hyperbolic-sine implementation that uses bit inspection plus `logf`, `log1pf`, `sqrtf`, and `force_eval!` for numerical edge cases. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `src/math/libm_math/k_sinf.rs`, which is a small sine-kernel math routine with fixed polynomial constants and a single pure computation path. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/math/libm_math/k_cosf.rs`, which is a small pure-Rust cosine kernel using fixed polynomial coefficients and a single arithmetic function. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `src/math/libm_math/sinhf.rs`, which is a straightforward `f32` hyperbolic-sine implementation using `expm1f` and `k_expo2f` with bit-level magnitude/sign handling. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
